Sounds like an aftermarket warranty to me. . Even a cpo warranty won't run till 2018 on a 2008.

Yes its an aftermarket warranty through Fidelity.

That's not what was asked...

The engine is not heavily modified. The engine is covered less the supercharger, unless the supercharger is determined to be what caused the failure. You can always take off the superchager and then not have to worry about that.
